Pneumatic Retinopexy Versus Pars Plana Vitrectomy for Rhegmatogenous Retinal Detachment: Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: This study aims to compare the outcomes of pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). MATERIALS AND METHODS: A systematic review and meta-analysis were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. An electronic search was conducted identifying six comparative studies of PnR versus PPV for RRD enrolling 1,061 patients. The primary outcome was visual acuity (VA). Anatomical success and complications were the secondary outcomes. RESULTS: No statistically significant difference was observed in VA between the groups. There was a statistically significant difference in the odds of re-attachment favoring PPV over PnR (odds ratio [OR] = 0.29, P < 0.00001). No statistically significant difference was found in final anatomical success (OR = 1.00, P = 1.00) and the development of cataracts (OR = 0.34, P = 0.61). Other complications, including retinal tears and postoperative proliferative vitreoretinopathy, were more frequently reported in the PnR group. CONCLUSION: PPV has a higher rate of primary reattachment compared to PnR for treating RRD with comparable final anatomical success, complications, and VA outcomes.

Paediatric case of peripapillary choroidal neovascularisation associated with optic disc drusen treated with aflibercept.

Peripapillary choroidal neovascularisation (PPCNV) associated with optic disc drusen is a rare complication that can result in severe vision impairment in children. We report the first case of paediatric PPCNV secondary to optic disc drusen successfully treated with intravitreal aflibercept. A 6-year-old girl presented with a one week history of reduced vision in her right eye with best-corrected visual acuity of 20/500. Fundus examination revealed bilateral elevated discs with a peripapillary pigmentary lesion in the right eye. Optical coherence tomography of the right eye showed marked subfoveal fluid. Both B-scan ultrasonography and fundus autofluorescence demonstrated findings consistent with optic disc drusen. Diagnosis of PPCNV was further confirmed on fluorescein fundus angiography. The child received three intravitreal aflibercept injections with complete resolution of the subfoveal fluid. Her visual acuity improved to 20/25 with no recurrence at a 16-month follow-up. No adverse side effects were reported.

Silent sinus syndrome as a recognised cause of unilateral painless enophthalmos.

An uncommon case of unilateral painless enophthalmos in a 44-year-old woman is presented. Despite the noticeable orbital asymmetry caused by enophthalmos, the patient has normal visual acuities in both eyes with unremarkable ophthalmic examination. Diagnosis of silent sinus syndrome was confirmed on the CT orbits and paranasal sinuses, showing complete opacification and atelectasis of the maxillary sinus. The patient achieved satisfactory improvements in her nasal symptom and facial appearance following functional endoscopic sinus surgery.

Serpiginous-like choroiditis as a marker for tuberculosis in a non-endemic area.

AIM: To describe the increasing incidence of multifocal outer retinal and inner choroidal inflammation as a marker for intraocular tuberculosis in the UK, a non-endemic area. PATIENTS AND METHODS: Retrospective case series. RESULTS: 14 patients presented with serpiginous-like choroiditis over 10 years (seven within the last 2 years). Seven of 14 patients showed evidence of exposure to tuberculosis and received antituberculous treatment. 17 of 23 eyes showed stable or improved visual acuity. All with decreased acuity had direct macular involvement at presentation. CONCLUSIONS: Multifocal outer retinal and inner choroidal inflammation is a marker for intraocular tuberculosis of increasing importance, even in a non-endemic area. Originally described as 'serpiginous-like choroiditis', the lesions are multifocal, irregular in shape, very numerous, widespread, often asymmetrical and often demonstrating both active and resolved lesions simultaneously. Active lesions show contiguous extension. We recommend that every patient with SLC should undergo testing for previous exposure to tuberculosis, and undergo antituberculous treatment if lesions are progressive and sight-threatening.
