Long-term follow-up of lamellar macular holes and pseudoholes over at least 5 years.

PURPOSE: To assess morphological and functional changes of lamellar macular holes and pseudoholes with or without vitrectomy and membrane peeling with at least 5 years follow-up. METHODS: Retrospective study of 73 eyes with lamellar macular hole (LH, n = 28), macular pseudohole (PH, n = 31), and pseudohole with cleaved edges (cleavedPH, n = 14). Forty-six eyes were merely observed without vitreoretinal intervention (observation group), and 27 eyes underwent vitrectomy with membrane peeling (vitrectomy group). Outcome measures were best corrected visual acuity (BCVA) and morphological retinal parameters evaluated with optical coherence tomography (TD-OCT and SD-OCT). RESULTS: Mean follow-up was 8.3 years (5-12); mean age was 67 years (46-84). In the observation group, median BCVA (logMAR) at first exam was 0.2 (LH), 0.1 (PH), 0.2 (cleavedPH) and at last exam 0.3 (LH, p = 0.02), 0.2 (PH), 0.15 (cleavedPH). In the vitrectomy group, median BCVA at first exam was 0.4 (LH), 0.3 (PH), 0.25 (cleavedPH); before vitrectomy BCVA was 0.5 (LH), 0.35 (PH), 0.35 (cleavedPH); and at last exam BCVA increased to 0.3 (LH), 0.2 (PH, p < 0.05), 0.1 (cleavedPH, p < 0.05). At last exam, BCVA of LH was significantly worse compared to PH and cleavedPH. In the observation group, 6 of 29 eyes with PH or cleavedPH showed a spontaneous resolution of the epiretinal membrane with improvement of the foveal contour. Nine of 16 eyes with LH and 2/20 eyes with PH presented lamellar hole-associated epiretinal proliferation (LHEP) in SD-OCT. CONCLUSIONS: LH, PH, and cleavedPH are often stable over a very long time. LH tends to worse visual function compared to PH and cleavedPH. A spontaneous separation of epiretinal membranes in the long-term is not uncommon. Vitreoretinal intervention should be considered in cases with significant visual loss or functional and morphological progression.

[Orbital screwdriver injury in a toddler]. / Orbitale Schraubenzieherverletzung bei einem Kleinkind.

Presentation of a patient with an orbital intracranial penetrating screwdriver injury. The patient had been playing with the screwdriver at the time of the accident, he fell and the screwdriver penetrated his right orbit. Imaging revealed the position of the foreign body, which went from the medial orbital wall, extraconal and medial of the right internal carotid artery, through the sella turcica to the dorsum sellae. The patient had no intracranial hemorrhage. There was hardly any bleeding. The surgical removal of the screwdriver was carried out without complications.

The role of pigment epithelial detachment in AMD with submacular hemorrhage treated with vitrectomy and subretinal co-application of rtPA and anti-VEGF.

PURPOSE: To assess the incidence of pigment epithelial detachment (PED) in age-related macular degeneration (AMD) with submacular hemorrhage (SMH) and its response to treatment with pars plana vitrectomy (ppV), subretinal co-application of recombinant tissue plasminogen activator (rtPA) and anti-VEGF, and an intravitreal gas tamponade. METHODS: Consecutive interventional case series of 132 eyes of 129 patients with neovascular AMD with SMH. All eyes underwent ppV with subretinal co-application of rtPA and bevacizumab followed by a gas tamponade. Postoperatively, two additional intravitreal anti-VEGF injections were applied monthly, followed by intravitreal anti-VEGF injections applied PRN thereafter. PEDs and SMHs were evaluated with SD-OCT pre- and postoperatively. RESULTS: Preoperatively, 88 of 132 (67%) eyes were examined by OCT, and in 81 of these eyes the RPE could be visualised. A PED was found in 74 (91%) eyes, and no PED was found in five (6%) eyes. Median height of preoperative PED was 503 µm (range 150-1242, n = 65) and reduced to 344 (n = 62) and 306 µm (n = 27) after 3 and 12 months respectively. Two eyes showed a pre-existing rip of the RPE. Postoperatively, a rip was documented in 12 of 128 (9%) eyes. Median height of SMH was 762 µm (range 217-1840), median diameter was 4.3 (1.5-15) disc diameter. A complete displacement of the SMH from the fovea was achieved in 112 of 129 (87%) eyes. Overall, median best-corrected logMAR visual acuity (BCVA) improved significantly from preoperative 1.6 (0.5-2.0, n = 132) to 1.0 (0.2-2.0) 3 (n = 132) and 12 months (n = 74) postoperatively. Excluding eyes with pre-existing macular scars (n = 22), BCVA 3 months postoperatively was 0.8. Height of PED or SMH did not correlate with postoperatively BCVA, while size of SMH showed a mild correlation (rho = 0.25, p = 0.005). CONCLUSION: PpV with subretinal co-application of rtPA and bevacizumab and an intravitreal gas tamponade effectively displaces SMH and improves BCVA. Preoperatively, PED is found in the majority of eyes. Height of PED or SMH did not correlate with postoperatively BCVA. Tears of the RPE occur as frequently as in exudative AMD without SMH.

[Retrospective case analysis of ophthalmological and systemic risk factors in patients with retinal vascular occlusion]. / Retrospektive Fallanalyse zum ophthalmologischen und internistischen Risikoprofil von retinalen Gefässverschlüssen.

OBJECTIVE: The aim was to determine systemic risk factors for acute central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) and to evaluate the usefulness of systemic diagnostics in CRAO and CRVO. METHODS: The study consisted of a retrospective chart review including 80 patients (CRAO 38, CRVO 42). All patients underwent systemic diagnostics including blood pressure measurement, blood cholesterol level, carotid Doppler imaging, transthoracic echocardiography (TTE), intraocular pressure measurement, glaucoma history and presence of thrombophilic factors. A systemic medical history was obtained. RESULTS: Systemic hypertension was found in 76.3% CRAO and 75.6% CRVO patients. Abnormal cardiac findings were detected in 61% (CRAO) and 22% (CRVO). Abnormal carotid findings were detected in 44.1% for CRAO and 9.5% for CRVO. Pathological thrombophilic factors were found in both groups for approximately 15%. CONCLUSIONS: TTE and carotid Doppler are important tools in the diagnosis of sources of emboli in patients with CRAO, while for CRVO abnormal findings are revealed by TTE and carotid Doppler less often. Thrombophilia should be ruled out in the absence of common risk factors, especially in younger patients and systemic hypertension should be adequately controlled.
