PurposeThis study compares the presence of vitreous hyper-reflective dots (VHDs) detected with optical coherence tomography (OCT) between eyes with pseudophakic cystoid macular edema (CME) and those with no CME after cataract surgery. In addition, we evaluated the impact of VHDs on the responsiveness of pseudophakic CME to cortisone treatment.SettingDepartment of Ophthalmology, Medical University of Graz, Austria.DesignRetrospective, monocenter case-controlled study.MethodsInclusion criteria for the study group and the control group were CME and no CME within 12 weeks following uneventful phacoemulsification in otherwise healthy eyes, respectively. VHDs (number and size) and the macular thickness were assessed with OCT. Furthermore, the number of peribulbar or intravitreal steroid injections was assessed.ResultsA total of 284 eyes from 267 patients were analyzed, among which 119 met the inclusion criteria for the study (n = 63) and the control group (n = 56). VHDs were observed in 54 (85.7%) study eyes and 21 (37.5%, p = 0.013) control eyes. The number of VHDs was 3.9±3.4 in the study group and 0.7±1 in the control group (p<0.001). The size of the VHDs was 33.5±9.1 μm and 36.6±17.9 μm in the study and control groups, respectively (p = 0.978). Overall, the number of VHDs correlated with central subfield thickness (r = 0.584, p<0.001), cube volume (r = 0.525, p<0.001), and postoperative best-corrected visual acuity (BCVA) (r = -0.563, p<0.001). The number of VHDs did not correlate with the frequency of peribulbar or intravitreal steroid injections.ConclusionVHDs occurred more often in eyes with CME than in eyes without CME following cataract surgery. In addition, the number of VHDs had an impact on the extent of macular thickening and subsequently postoperative BCVA. No correlation was found between the number of VHDs and the frequency of required peribulbar or intravitreal steroid injections.
In this study, an increase in SRF was associated with an increase in both choroidal thickness and volume in eyes with treatment-naïve CSC. Eyes with thicker baseline choroidal volume showed a greater reduction in SRF.
Purpose: To present a case of unilateral stellate nonhereditary idiopathic foveomacular retinoschisis in a patient with macular telangiectasia (MacTel) Type 2.Methods: Single-patient case report.Results: A 61-year-old female white patient was referred to our clinic with metamorphopsia and reduction of visual acuity over a period of 2 months on her right eye. Ocular findings in her right eye included reduced best-corrected visual acuity of 20/ 63 Snellen, foveomacular retinoschisis with extension to the lower middle periphery, central elevation of the neurosensory retina, and macular telangiectasia (MacTel) Type 2. Other causes of foveomacular retinoschisis, such as glaucoma, myopic degeneration, optic or scleral pit, X-linked juvenile retinoschisis, degenerative retinoschisis, and vitreomacular traction, were ruled out. The patient had no history of niacin or taxane medication, which may cause rather similar appearing cases of cystoid macular edema without leakage in fluorescein angiography. Because of the unilateral presentation, uneventful medical history, female sex, and the absence of known hereditary diseases or retinal pathologies in the patient's family history, hereditary predisposition appears to be highly unlikely.Conclusion: To our knowledge, this is the first reported case of stellate nonhereditary idiopathic foveomacular retinoschisis in combination with MacTel Type 2. Whether or not MacTel Type 2 plays a role in the development of stellate nonhereditary idiopathic foveomacular retinoschisis or has an impact on its clinical course requires further investigation. Furthermore, we suggest a significant involvement of Henle fiber layer in the process of intraretinal expansion in optical coherence tomography, in accordance with the most recent published nomenclature.
The macular choroidal volume and the subfoveal choroidal thickness decreased significantly after 3 monthly bevacizumab injections for exudative age-related macular degeneration.
