The authors report the anatomical and functional response to topical use of carbonic anhydrase inhibitor (CAI) in the treatment of foveoschisis in a case of X-linked juvenile retinoschisis (XLJR). A 9-year-old boy with visual impairment in both eyes, was admitted to Hilton Rocha Fundation ophthalmologic clinic. Fundus examination revealed radial cystoid appearance in a petaloid configuration in the fovea, and retina pigment epithelium alterations at superior mid-peripheral retina in both eyes. Optical coherence tomography (OCT) showed foveal cystoid structures, loss of foveal depression and splitting at inner retinal layers in the macula. Following treatment with topical dorzolamide 2% for 7 months, there was dramatic regression of both macular and peripheral schisis cavities and improvement of visual acuity in both eyes.

Retinal vasoproliferative tumor (VPT) is uncommon retinal lesion, classified as primary (idiopathic) or secondary. Retinal VPT has a predilection for the peripheral inferior temporal quadrant of the retina and may be unilateral or bilateral. It can lead to decrease vision due to intraretinal or subretinal exudation, neovascularization, retinal detachment, vitreous hemorrhage, preretinal fibrosis, macular edema and epiretinal membrane formation. Different modalities have been used to treat this tumor including clinical observation, pars plana vitrectomy, cryotherapy, laser photocoagulation, brachytherapy and radiotherapy. The authors describe a case of idiopathic retinal VPT associated with extensive serous retinal detachment and point out the importance of diagnosis and the effectiveness of cryotherapy.
