RESUMO
PURPOSE: To compare the anatomical and functional outcome of adjuvant pars plana vitrectomy (PPV) procedures using the techniques of translocation of an internal limiting membrane (ILM) flap and transplantation of an inverted ILM flap for the treatment of chronic and/or refractory optic disc pit (ODP) maculopathy. METHODS: In this prospective interventional case series study, 9 patients (9 eyes) with chronic and/or refractory ODP maculopathy underwent PPV with either translocation of an ILM flap or transplantation of an inverted ILM flap as adjuvant techniques along with gas tamponade. The anatomical success, rates of macular reattachment, and visual improvement were assessed. RESULTS: The mean preoperative central retinal thickness (CRT) was 723.4 µm (range: 366-1,151). The mean postoperative CRT was 398.1 ± 212.2 µm (range: 210-758). An increased preoperative CRT was associated with a lower chance of postoperative reattachment of the macula (p = 0.047). The overall reattachment rate at the end of the follow-up period was 56% (n = 5). The mean preoperative visual acuity (logMAR unit [Snellen acuity]) was 0.48 (20/60) (range: 1.30 [20/400] to 0.10 [20/25]). The mean change in best corrected visual acuity (BCVA) was 0.48 ± 0.233 logMAR units (approx. 3 lines of visual improvement). CONCLUSIONS: ILM flap techniques are logical and straightforward approaches as adjuvants to PPV treatment of ODP maculopathy. They could be viable adjuvant treatments for improvement in BCVA and CRT in patients with ODP maculopathy.

PURPOSE: To evaluate the treatment outcomes of intravitreal bevacizumab injections as monotherapy in type 1 retinopathy of prematurity (ROP). METHODS: A retrospective chart review was performed for patients with type 1 ROP who had intravitreal bevacizumab injections between November 2013 and January 2015 at La Paz University Hospital in Madrid, Spain. Gestational age at birth, birth weight, sex, ROP zone, ROP stage, mean age at treatment, and follow-up period were recorded. The final clinical status of the retina was noted for each patient. The primary outcome measures included ROP recurrences requiring re-treatment, complete or incomplete peripheral vascularization, mean age at complete vascularization, and refractive errors. RESULTS: From 14 patients enrolled with type 1 ROP, 28 eyes were included. The mean gestational age at birth was 25.9 ± 2.34 weeks (range: 23.6 to 32.4 weeks) and the median birth weight was 694 g (range: 487 to 1,740 g). All eyes showed zone II ROP: 18 eyes (64.3%) had anterior zone II ROP and 10 eyes (35.7%) had posterior zone II ROP. One week after intravitreal bevacizumab injection, 14 eyes (50%) had achieved complete regression of ROP, and a partial regression of ROP was observed in 10 eyes (35.7%). Twenty-two eyes (78.6%) obtained complete vascularization during the follow-up. The median time to complete vascularization was 134 ± 21.45 days. The mean spherical equivalent at last visit was 1.99 diopters. CONCLUSIONS: Intravitreal bevacizumab injection used as a monotherapy is an effective treatment approach in patients with zone II ROP.

BACKGROUND: Alström syndrome is a rare genetic ciliopathy caused by a mutation in the ALMS1 gene. The syndrome is characterized by cone-rod dystrophy, dilated myocardiopathy, childhood obesity and sensorineural hearing loss. To date, cystoid macular edema has not been reported. METHODS: A female affected by Alström syndrome developed bilateral cystoid macular edema evidenced by optical coherence tomography. A topical carbonic anhydrase inhibitor was prescribed. RESULTS: Complete resolution of the cystoid macular edema was achieved, though visual acuity did not improve. CONCLUSIONS: Topical carbonic anhydrase inhibitors may have a role in the treatment of macular edema in syndromic retinal dystrophies such as Alström syndrome.

We report a case of an immunocompetent woman with atypical marginal keratitis. She presented with recurrent episodes of multiples microabscess distributed in a triangular pattern associated with stromal oedema and anterior chamber uveitis, affecting both eyes, but not simultaneously. The episodes responded to steroid drops, corneal inflammation was coincidental with a worsening of her blepharitis in the affected eye and S. aureus was isolated from the lids.

OBJECTIVES: The aim of this study is to report a case of conjunctival lymphangiectasia simulating a pediatric pterygium. METHODS: A 10-year-old girl with Turner syndrome and familial history of pterygia presented because of a conjunctival growing lesion clinically consistent with pterygium in her left eye. Visual acuity (VA) was 20/20 in the right eye and 20/40 in the left eye. Cycloplegic refraction was +1.50sph -0.50cyl×93° and +9.00sph -9.00cyl×180° in the right and left eyes, respectively. RESULTS: Resection of the lesion with amniotic membrane implantation and conjunctival autograft was performed. The histologic examination revealed conjunctival lymphangiectasia. Ten months later, the patient did not show any signs of recurrence. Refraction in the left eye was +0.5sph -1.5cyl×70°, and spontaneous VA was 20/20 in both eyes. CONCLUSIONS: Pediatric pseudopterygium may be the clinical presentation of several ocular surface disorders. Thus, pathologic analysis of this lesion should be considered to determine its exact nature. Surgery lessens the refractive defect and hastens visual recovery.

BACKGROUND: Microcephaly-lymphedema-chorioretinal dysplasia (OMIM 152950) is a rare malformative inherited disorder that can be associated with other systemic features. Other ocular and brain anomalies rather than microcephaly and chorioretinal dysplasia have been inconstantly reported in this syndrome. METHODS: We present a case of microcephaly-lymphedema-chorioretinal dysplasia with a dysmorphic facies, hypertonicity in the extremities and neuropsychomotor delay. Ophthalmological examination revealed bilateral nystagmus, microphthalmia, posterior subcapsular cataratacts, extensive chorioretinal dysplasia, optic nerve aplasia, persistent fetal vasculature, and absent retinal vessels. RESULTS: Magnetic resonance revealed pachymicrogyria and discrete atrophy of vermis cerebelosum and confirmed optic nerve hypoplasia. CONCLUSIONS: The developmental alterations observed in the retina of this patient could be analogous to central nervous system anomalies, reflecting a reduction in neural population. Ophthalmic examination of children with microcephaly is warranted.
