Lacrimal Canaliculitis: A Major Review

Lacrimal canaliculitis is an inflammation of the proximal lacrimal drainage system. It classically presents with symptoms of redness, mucopurulent discharge, medial canthal swelling, epiphora, and pouting punctum. Despite having classical clinical characteristics it is frequently misdiagnosed. The cause can be primarily due to various infectious agents or secondary mostly due to the use of punctal plugs. There are no universally accepted guidelines for the management of canaliculitis but different medical and surgical options have been employed with varying success rates and it is notorious for recurrences and failure to therapy. The present review summarizes the existing literature on lacrimal canaliculitis published over the past 15 years to provide an overview of this uncommon condition. A total of 100 articles published in the literature were anlaysed during this period. The mean age at diagnosis was 57.09 ± 16.91 years with a female preponderance. Misdiagnosis was common with many patients misdiagnosed as conjunctivitis and dacryocystitis. Primary canaliculitis was found to be more frequent than secondary with inferior canaliculus involved more commonly than the superior. Staphylococcus, Streptococcus, and Actinomyces were the most common microbes isolated. Surgical management was employed in 74.25% of cases while medical management was done in 20.82% of cases. The review presents an insight into the complexities of canaliculitis, its diagnosis, and management which will further help to improve the understanding of this uncommon infection of the lacrimal system.

Eccrine spiradenoma of eyelid - a rare tumor at an unusual location with literature review

Eccrine spiradenoma is a rare sweat gland tumor and usually presents as a solitary, painful nodule. A solitary spiradenoma involving the eyelid is quite rare. A 39-year-old Indian female presented with a gradually increasing, painless, nodular upper eyelid mass for the past 4 years. On examination, a non-tender approximately 4 × 3 mm cystic mass was noted, which was not adherent to underlying structures. The mass was excised in toto, and the histopathological examination was suggestive of eccrine spiradenoma with a low Ki-67 index. The patient was doing well without any signs of recurrence at 2 months of follow-up.

Congenital orbital fibrosis: report of two cases and review of literature

A 7-year-old male child presented with complaints of lagophthalmos and lid retraction of the right eye since birth. Magnetic resonance imaging (MRI) showed diffuse thickening of right superior rectus and levator-palpebrae complex along with a hypointense, irregular, and ill-defined lesion in the adjoining fat abutting the lacrimal gland. Biopsy from the lesion showed diffuse orbital fibrosis. Another 3-year-old female child presented with complaints of her right eye appearing smaller and inability to move the right eye freely since birth. MRI showed thickening of right superior and medial recti with diffuse retrobulbar hypointense fibrotic strands. The findings were suggestive of orbital fibrosis. Congenital orbital fibrosis is an extremely rare orbital pathology with very few cases described in the literature. The most common clinical features are motility restriction, restrictive strabismus, upper lid retraction, enophthalmos, and proptosis. The diagnosis can be made on imaging but requires biopsy for confirmation. Management is mostly conservative in the form of refractive and amblyopia therapy.

Clinical and histopathological profile of primary caruncular lesions

Purpose

To provide a retrospective analysis of lesions of the caruncle which have been very rarely reported in the literature.

Methods

A retrospective review of all the caruncular lesions between January 2000 and January 2020 was done at a single tertiary eye care hospital. The lesions were classified as benign and malignant lesions. Clinicopathological correlation was done for the excised lesions.

Results

A total of 87 caruncular lesions were included in the study. Males (59%) were affected more than females (41%). The mean age at presentation was 44 ± 20 years. The mean duration of complaint was 36 ± 62 months. A total of 36 patients underwent surgical excision whereas the rest opted for conservative management. Recurrence was noted in five patients. Fifteen different types of lesions were identified histopathologically. Benign lesions (78%) were far more common than malignant ones (22%). Epithelial inclusion cyst was the most common benign lesion and sebaceous gland carcinoma was the most common malignant lesion. Correct clinicopathological correlation was seen in 52.7% of the cases. Caruncular tuberculosis, oncocytoma, and basosquamous cell carcinoma were some of the rare lesions.

Conclusion

Caruncular lesions are uncommon and very diverse, which makes clinical diagnosis challenging. Epithelial inclusion cyst and sebaceous gland carcinoma were the most common benign and malignant lesions respectively. Correct clinicopathological correlation was seen in more than half of the cases.

The prevalence and risk factors for age-related macular degeneration in rural-urban India, Sankara Nethralaya Rural-Urban Age-related Macular degeneration study, Report No. 1

PurposeTo report the age- and gender-adjusted prevalence rates of early and late age-related maculopathy (ARM) and associated risk factors in rural and urban Indian population.MethodsA population-based cross-sectional study was carried out in South India between 2009 and 2011. Of the 6617 subjects ≥60 years enumerated ones, 5495 (83.04%) participated in the eye examination. A detailed history including data on demographic, socioeconomic, and ocular history was obtained. Participants underwent detailed ophthalmic evaluation including 30° 3-field photograph as per Age-Related Eye Disease Study protocol. The ARM was graded according to the International ARM Epidemiological Study Group.ResultsAge- and gender-adjusted prevalence of early ARM was 20.91% (20.86-20.94) in the rural population and 16.37% (16.32-16.42) in the urban population. Similarly, the prevalence of late ARM was 2.26% (2.24-2.29) and 2.32% (2.29-2.34) in the rural and urban population, respectively. In both rural and urban populations, risk factors that were related to both early and late ARM were age, per year increase (OR, range 1.00-1.08); middle socioeconomic status (OR, range 1.05-1.83); and smokeless tobacco (OR, range 1.11-2.21). Protective factor in both was the presence of diabetes mellitus in all ARM (OR, range 0.34-0.83). Risk factors, only in the rural arm, were female gender (OR, range 1.06-1.64), past smoker (OR, 1.14), and serum low-density lipoprotein cholesterol level (OR, 1.03).ConclusionsThe study reports smokessless tobacco as a risk factor for both early and late ARM and identified a higher prevalence of early ARM in the rural population compared with urban population.

Endophthalmitis caused by Acinetobacter baumanni: a case series

PURPOSE

To profile the etiology, clinical outcomes and drug sensitivity patterns in endophthalmitis caused by Acinetobacter baumanni.

METHODS

Retrospective analysis of all the cases of Acinetobacter baumanni endophthalmitis presenting to tertiary referral care ophthalmic hospital in Eastern India from January 2009 to December 2011 were done.

RESULTS

A total of four cases were included in the study. Out of the four cases one was post traumatic and the rest were post cataract surgery. All the cases underwent vitreoretinal surgical intervention followed by intravitreal antibiotics. A. Baumanni was isolated from vitreous in all the cases. Among all the drugs tested bacteria were found sensitive to ciprofloxacin (100 %) whereas all tested resistant to ceftazidime. Out of the four cases one had to be eviscerated, another developed retinal detachment post vitrectomy, one was phthisical at final followup, and only one patient achieved a vision of 20/200 with clear media and attached retina at final visit.

CONCLUSION

A. Baumanni is a very rare cause of endophthalmitis with poor visual and anatomical outcomes. Ciprofloxacin should be considered as first the line intravitreal antibiotic.

Psoralen-ultraviolet A therapy vs. psoralen-ultraviolet B therapy in the treatment of plaque-type psoriasis: our experience with fitzpatrick skin type IV

BACKGROUND

Oral psoralen, when combined with UVB, shows an increased response in psoriasis. In this study, conventional psoralen-UVA (PUVA) therapy was compared with psoralen-UVB (PUVB) therapy in plaque-type psoriasis in patients with Fitzpatrick skin type IV.

PATIENTS AND METHODS

Equal numbers of patients with stable, plaque-type psoriasis were treated with either PUVA (n = 22) or PUVB (n = 22), three times weekly until 90% clearance was achieved. A final evaluation was made 3 months later.

RESULTS

The two groups showed no significant differences in terms of clearance of disease, mean number of exposures, or the average duration of therapy; however, the cumulative dose of UVB required for clearance was significantly lower than that of UVA. Both groups had a similar acute side-effects' profile.

CONCLUSIONS

PUVB therapy is as effective as conventional PUVA in the treatment of stable, plaque-type psoriasis in patients with Fitzpatrick skin type IV. A significantly lower dose of UVB is required for clearance as compared with UVA.
