Empowering patients with high myopia: The significance of education

PURPOSE

To investigate the status of patient education among highly myopic individuals focusing on the presence, sources, content, timing of the education and impact on patients.

METHODS

Self-reported data were collected through an online 13-item questionnaire consisting of open and multiple-choice questions. The questionnaire was sent to 250 highly myopic members of a patient organization in the Netherlands, of whom 128 (51%) responded.

RESULTS

At least one acute event had occurred in 66% (84/128) of participants at the time of the questionnaire. Among all participants, 25% (32/128) had not received patient education regarding alarm symptoms for any of these events. Among those who had been informed, the ophthalmologist was the most frequent (57%, 73/128) source of information. Participants who visited the ophthalmologist annually were more frequently informed than participants without annual visits (53%, 26/49 versus 26%, 9/35, p = 0.002). Those not informed were more likely to have a more than 3 days patient delay (92%, 12/13). Doctors delay was also present; 26% (22/84) of the participants with alarm symptoms had to wait 2 or more days before the first appointment. Long-term consequences of myopia had been discussed with 102 participants (80%, 102/128), again with the ophthalmologist as the most frequent source (59%, 76/128).

PERSPECTIVES

Many myopic individuals have not been educated about their increased risk of acute events, which can result in patient delay and serious consequences with respect to visual prognosis. These findings underscore the critical importance of integrating patient education across the entire ophthalmic care chain for myopia.

Staphyloma-induced Serous Maculopathy: Natural Course and Treatment Effects

PURPOSE

To study the natural course of staphyloma-induced serous maculopathy (SISM) and the effects of treatments.

DESIGN

Retrospective case series.

PARTICIPANTS

This retrospective analysis included 26 eyes of 20 patients with SISM and at least 12 months of follow-up.

METHODS

Medical records were reviewed for patient demographics, such as age, sex, spherical equivalent, best-corrected visual acuity (BCVA), type of staphyloma, and imaging characteristics. Spectralis OCT B-scans were evaluated for the presence and height of the serous retinal detachment (SRD) at each follow-up visit. An SRD episode was defined as a period with SRD in 1 patient.

MAIN OUTCOME MEASURES

Changes in SRD height and BCVA.

RESULTS

Twenty-six eyes of 20 patients (70% female) were included. The mean age was 54 ± 11 years, and the mean spherical equivalent was -4.8 ± 3.3 diopters at baseline. The staphyloma was located inferior in 12 eyes (46%), inferonasal in 7 eyes (27%), and nasal in 7 eyes (27%). The mean follow-up duration was 73 ± 34 months. During follow-up, the SRD height fluctuated in all eyes, with a mean change of 125 ± 56 μm. The SRD disappeared completely during follow-up in 13 eyes (50%) and then reappeared in 7 eyes (35%). Resolution occurred spontaneous in 8 eyes (31%). The median time of an SRD episode was 25 (interquartile range 14-57) months. Treatment was performed in 20 eyes (77%) and led to resolution of SRD in 3 of the 15 photodynamic therapy treatments (21%), 2 of 5 (40%) anti-VEGF series, and 2 of 4 eyes (50%) treated with topical prednisolone. Best-corrected visual acuity at the final visit (0.42 ± 0.25) was not significantly different from BCVA at baseline (0.34 ± 0.27 logarithm of the minimum angle of resolution, P = 0.07), nor was BCVA change significantly different between treated eyes (n = 19) and nontreated eyes (n = 7, P = 0.3).

CONCLUSION

Serous retinal detachment in patients with SISM fluctuated over time and resolved without treatment in 31% of the eyes. Because treatment does not change the course of BCVA, a wait-and-see policy is advocated in these patients on the exclusion of treatable causes of SRD.

Incidence and Risk Factors of Second Eye Involvement in Myopic Macular Neovascularization

PURPOSE

To report the cumulative incidence and risk factors of second eye involvement after diagnosis of myopic macular neovascularization (MNV) in the first eye.

DESIGN

Retrospective analysis of longitudinal data from a tertiary hospital in the Netherlands.

PARTICIPANTS

Patients with high myopia (spherical equivalent [SE] ≤ - 6 diopters [D]), of European ethnicity, who were diagnosed with active MNV lesion in 1 eye between 2005 and 2018. Fellow eyes were free of MNV or macular atrophy at baseline, and data were collected on the SE, axial length, and presence of diffuse or patchy chorioretinal atrophy and lacquer cracks.

METHODS

Incidence rate and 2-, 5-, and 10-year cumulative incidences were calculated; hazard ratios (HRs) of second eye involvement were analyzed for potential risk factors using Cox proportional hazard models.

MAIN OUTCOMES MEASURES

Incidence of second eye involvement after onset of myopic MNV in the first eye.

RESULTS

We included 88 patients over a period of 13 years with a mean age of 58 ± 15 years, mean axial length of 30 ± 1.7 mm and SE -14 ± 4 D at baseline. Twenty-four fellow eyes (27%) developed a myopic MNV during follow-up. This resulted in an incidence rate of 4.6 (95% confidence interval [CI], 2.9-6.7) per 100 person-years and a cumulative incidence of 8%, 21%, and 38% at 2, 5, and 10 years, respectively. Mean time until MNV development in the fellow eye was 48 ± 37 months. Patients aged < 40 years at the initial presentation had a 3.8 times higher risk of bilateral myopic MNV (HR, 3.8; 95% CI, 1.65-8.69; P = 0.002). The presence of lacquer cracks in the second eye seemed to increase risk, but this did not reach statistical significance (HR, 2.25; 95% CI, 0.94-5.39; P = 0.07).

CONCLUSIONS

Our study of high myopes of European descent shows very similar incidence rates for second eye myopic MNV compared with Asian studies. Our findings substantiate the importance for clinicians to monitor closely and create awareness, especially in younger patients.

LONG-TERM TREATMENT OUTCOMES AFTER BEVACIZUMAB THERAPY FOR MACULAR NEOVASCULARIZATION IN WHITE PATIENTS WITH HIGH MYOPIA

PURPOSE

To report long-term treatment outcomes of intravitreal bevacizumab in myopic macular neovascularization (MNV).

METHODS

Retrospective analysis of longitudinal, clinical data of patients with high myopic MNV treated with intravitreal bevacizumab. One-hundred and seventeen eyes of 106 patients were followed from first injection up to 12 years. Outcome measures were best-corrected visual acuity change during follow-up and myopic MNV recurrence.

RESULTS

Mean (±SD) baseline best-corrected visual acuity (0.56 ± 0.46 logMAR, 20/80) significantly improved after first treatment (0.33 ± 0.33, 20/50, P < 0.001). At 4 years (n = 86), best-corrected visual acuity was no longer significantly better than at baseline (0.55 ± 0.57, P = 0.30) and continued to deteriorate to 0.84 ± 0.76 (20/125) at 10 years (n = 27). Of the 27 eyes (23%) who reached 10 years of follow-up, 53% developed MNV-related chorioretinal atrophy. The cumulative incidence of recurrent myopic MNV was 34% at 2 years and 59% at 5 years. Best-corrected visual acuity decrease in eyes with or without recurrent MNV was similar ( P = 0.58). Patchy chorioretinal atrophy (hazard ratio 3.0, P = 0.02) and subfoveal MNVs (hazard ratio 2.5, P = 0.048) were significantly associated with recurrent MNV.

CONCLUSION

This retrospective myopic MNV study revealed that visual improvement after intravitreal bevacizumab injections was not maintained over time. Macular neovascularization recurrences occurred frequently but did not alter the already poor visual prognosis.

A view from the clinic - Perspectives from Dutch patients and professionals on high myopia care

PURPOSE

To understand and compare perspectives of patients and professionals on current ophthalmologic care for high myopia, and to identify challenges and future opportunities.

METHODS

Self-reported data were collected through two online questionnaires. Patient perspective was obtained from highly myopic members of a patient organisation based in the Netherlands using a 17-item questionnaire consisting of open and multiple-choice questions regarding personal experience with myopia care. The ophthalmologist perspective was obtained from practising Dutch ophthalmologists with a 12-item questionnaire of multiple-choice questions on work-related demographics, myopia care in daily practice and need for improvement. The response rate for patients was 27% (n = 136/500) and for ophthalmologists, 24% (n = 169/716).

RESULTS

Patients were highly concerned about personal progressive loss of vision (69%) and feared their psychological well-being (82%) in case this would happen. The quality of performance of care provided by ophthalmologists was rated as excellent or satisfactory by 64% of the patients. These ratings for multidisciplinary care and insurance reimbursement were as low as 28% and 18% respectively. The mean concern among ophthalmologists about the rise in high myopia was 6.9 (SEM 0.1) on a 10-point scale. Sixty-nine per cent of the ophthalmologists reported that asymptomatic myopic patients should not be examined regularly at outpatient clinics. Ophthalmologists urged the development of clinical guidelines (74%), but did report (95%) that they informed patients about risk factors and complications. This contrasted with the view of patients, of whom 42% were discontent with information provided by ophthalmologists.

CONCLUSIONS

These questionnaires demonstrated that the current clinical care delivered to highly myopic patients is in need of improvement. The expected higher demand for myopia care in the near future requires preferred practice patterns, professionals specifically trained to manage myopic pathology, accurate and comprehensive information exchange and collaboration of in- and out-of-hospital professionals across the full eye care chain.

MYOPIC PRESENTATION OF CENTRAL SEROUS CHORIORETINOPATHY

PURPOSE

To increase insight into the myopic presentation of central serous chorioretinopathy (CSC) by comparing a large group of myopic patients with CSC with reference groups with only one of the diagnoses.

METHODS

Myopic patients with CSC (spherical equivalent ≤-3D, n = 46), emmetropic patients with CSC (spherical equivalent -0.5 to 0.5 D, n = 83), and myopic, non-CSC patients (n = 50) were included in this multicenter cross-sectional study. Disease characteristics and imaging parameters, such as subfoveal choroidal thickness and indocyanine green angiography patterns, were compared between cases and reference groups.

RESULTS

In myopic patients with CSC, median subfoveal choroidal thickness (286 µm [IQR 226-372 µm]) was significantly thicker than subfoveal choroidal thickness in myopic, non-CSC patients (200 µm [IQR 152-228 µm], P < 0.001) but thinner than emmetropic patients with CSC (452 µm [IQR 342-538 µm], P < 0.001). They also had pachyvessels in 70% of the eyes comparable with emmetropic CSC (76%, P = 0.70). Choroidal hyperpermeability was frequently present on indocyanine green angiography in both myopic and emmetropic CSC eyes. Need for treatment, treatment success, and recurrence rate were not significantly different between CSC groups.

CONCLUSION

Myopic CSC presents with similar imaging and clinical characteristics as emmetropic CSC, apart from their thinner choroids. Keeping in mind the structural changes of myopia, other imaging characteristics could aid the diagnostic process.
