Case Report of a Family Affected by Stickler Syndrome in Which Rhegmatogenous Retinal Detachment Occurred in Five Eyes of Three Siblings

Nonperfusion of the Far Peripheral Retina in Highly Myopic Stickler Syndrome

Purpose: To describe the clinical course of 3 patients with Stickler syndrome found on fluorescein angiography (FA) to have nonperfusion of the peripheral retina. Methods: Three patients with confirmed Stickler syndrome were examined under anesthesia. Genetic testing and FA were performed. Results: Each patient had characteristic ocular findings of Stickler syndrome, including high myopia with vitreoretinal degeneration. FA was performed on each patient and showed 360 degrees of nonperfusion of the retinal periphery in all eyes, with mild leakage in Case 3. Conclusions: The current series presents evidence of peripheral retinal nonperfusion in 3 consecutive patients with Stickler syndrome. Based on these findings, the authors recommend adopting FA as a standard imaging modality and using laser photocoagulation to treat the areas of retinal nonperfusion for all patients with Stickler syndrome.

Retinal detachment with multiple macrocysts in Stickler syndrome: case report and review of the literature

Background

Stickler syndrome is a hereditary connective tissue disorder associated with ocular, orofacial, musculoskeletal, and auditory impairments. Its main clinical characteristics include retinal detachment, hearing loss, and midface underdevelopment. In clinical practice, macrocyst is rarely reported in retinal detachment cases with Stickler syndrome.

Case presentation

We report the case of a 7-year-old child who developed a rhegmatogenous retinal detachment (RRD) in the right eye, accompanied by multiple peripheral macrocysts. The detachment was successfully surgically repaired with vitrectomy, retinal laser photocoagulation, cryotherapy and silicone oil tamponade. During the operation, a mini-retinectomy in the outer layer of each macrocyst was made for vesicular drainage and retinal reattachment. Genetic testing identified a pathogenic point mutation variant (c.1693C>T; p.Arg565Cys) in exon 26 of the COL2A1 gene. Six-months after the operation, the retina remained attached with improvement of best corrected visual acuity to 20/200.

Conclusion

Patients with Stickler syndrome may develop RRD of different severity. Macrocyst is rarely reported in previous literature of Stickler syndrome. In this case report, we share our experience in treating with multiple macrocysts in RRD and emphasize the importance of periodic follow-up for patients with Stickler syndrome.

Feeding Difficulty in an Infant with Stickler's Syndrome

Stickler syndrome or hereditary progressive arthro-ophthalmopathy is an autosomal dominant condition characterized by ocular manifestations, arthritic changes, orofacial features, and deafness, in variable degrees. This is a case report of a 48-day-old infant who presented with severe feeding difficulty. It also details the clinical, diagnostic features, and management of an infant with Stickler syndrome.
