Intravitreal dexamethasone implant as an option for anti-inflammatory therapy of tuberculosis uveitis.

INTRODUCTION: Tuberculosis-associated uveitis remains a diagnostic and therapeutic challenge. After diagnosis of tuberculosis and initiation of anti-tuberculosis therapy for tuberculosis uveitis, the clinical responses are favorable. However, at 4-6 weeks of the therapy, there commonly occurs paradoxical deterioration due to an increase in inflammation which is often accompanied by cystoid macular edema. Thus, adjuvant administration of anti-inflammatory regimen should be considered. For this purpose, systemic and periocular steroids, systemic and intravitreal immunosuppressive agents have been tested. Nevertheless, there is no report in the literature about intravitreal dexamethasone slow-release implants for the treatment of this inflammatory condition. METHODS: Case presentation. RESULTS: We presented a tuberculosis uveitis case whose ocular inflammation is partially modified by systemic and periocular steroid injections and then well controlled by the intravitreal dexamethasone implant. CONCLUSION: Intravitreal dexamethasone implant injection seems to be a safe and potent option for the treatment of macular edema secondary to tuberculosis uveitis.

Acute lupus choroidopathy: multimodal imaging and differential diagnosis from central serous chorioretinopathy.

IMPORTANCE: Systemic lupus erythematosus (SLE) is a thoroughly examined multi-organ disease whose common ocular complications are also well documented. However, SLE choroidopathy, being a rare ocular complication, is needed to be better understood, in order to make the differential diagnosis from clinical conditions such as central serous chorioretinopathy and provide adequate prompt treatment. OBJECTIVE: To provide a clear understanding for the clinical course of SLE choroidopathy by the help of enhanced depth imaging optical coherence tomography, fluorescein angiography, and indocyanine angiography. DESIGN: The study is designed as a case presentation, consisting of the physical examination results and the data gathered by the relevant screening methods for each visit, applied by the same ophthalmologists and technicians. SETTING: The visits were organized as same day examinations as needed, in a university hospital which works as a referral center.

Flap-Related Complications Following Temporal Inverted Internal Limiting Membrane Flap for Macular Hole Repair.

Here we report three cases of flap-related complications following temporal inverted internal limiting membrane (ILM) flap technique for the repair of macular holes (MH). The first case showed a flap closure pattern in which the MH completely closed at 2 months spontaneously. The second case showed early anatomical and functional improvement provided by an immediate closure of the MH but developed flap contracture and nasally located epiretinal membrane (ERM) at postoperative 18 months. There was no functional deterioration, thus no further intervention was required. In the third case, early postoperative flap dislocation was observed and an additional surgery to reposition the flap was needed. The flap closure pattern observed with inverted ILM flap techniques may represent the ongoing healing process of large MHs and may be related to delayed spontaneous anatomical closure. ILM flap contracture and ERM formation may be a harmless long-term complication. Dislocation of the ILM flap is an unexpected early postoperative complication that may necessitate a second surgery for flap repositioning.

Effects of Congenital Ocular Toxoplasmosis on Peripheral Retinal Vascular Development in Premature Infants at Low Risk for Retinopathy of Prematurity

Congenital toxoplasmosis and retinopathy of prematurity (ROP) are two devastating clinical entities of the newborn. There is little information in the literature about the interaction between congenital infections and retinal vascular development at the fetal stage, and none regarding the relationship between ROP and congenital toxoplasmosis. In this report, we present two premature newborns diagnosed with congenital toxoplasmosis with ocular involvement, accompanied by ROP with interrupted retinal vascularization, peripheral avascular regions, and retinal detachment. The aim of this paper is to emphasize the possibility of ROP and congenital toxoplasmosis coexistence wherein one condition may mask the other and make it difficult to distinguish the cause of retinal detachment. Timely management with medical and surgical treatment of congenital toxoplasmosis and ROP could save eyes and vision in those cases.
