Foveal Sparing

Foveal-sparing scotomas are common in advanced dry macular degeneration (geographic atrophy). Foveal preservation may be present for a number of years. Despite good visual acuity, these patients have reduced reading rates. Magnification may not be effective if the text becomes too large to “fit” within the central spared area.

Stargardt’S Disease

Visual disability affects about 2 million Poles. This group includes people who have been diagnosed with Stargardt’s disease. This disease occurs in the general population with a frequency of one in 10,000. It leads to legal blindness with visual acuity lower than 5%. Visual disturbances in this disease may occur in children, i.e. 7–12 years of age, as well as in adolescents and adults. People suffering from this disease experience a significant reduction in visual acuity, difficulty in recognizing colors, impaired depth vision, difficulties with accommodation, impaired central vision and often severe photophobia. The aim of the research was to collect information about the assistive technologies used by people with Stargardt’s disease and to identify their ability to move independently despite a significant reduction in visual acuity. The research results show that most of the 102 surveyed people use various types of assistive technology and experience significant visual impairment. At the same time, a significant part of this group declares that despite the inability to read the black print text, they can still move quite freely.

Objectives: To investigate the clinical characteristics of cataract patients with small pupils and to evaluate the result of cataract surgery on the eye have small pupils by phacotechnique. Subjects and methods: Descriptive study, prospective, uncontrolled interventions. Sample selection. The sample size of 70 patients with 70 eyes of cataracts with small pupils was treated by phaco technique and intraocular lens implant within posterior chamber. Follow up to 3 months. Results: 70 eyes, the percentage of men and women was not different from 54.2% (38 male) compared to 45.8% (32 female). The mean age was 80 ± 8.74, from 58 to 99 years. The disease was mainly found in the age group over 70 years old with over 80% (51.5%). Visual acuity before surgery was very poor under 3m CF (count finger) for 68.6% (48/70). Visual acuity over 1/10 was only a small amount with 2.8% (2 eyes). Pseudoexfoliation was the most common reason complications of mydriasis with 32/70 eyes (45.7%) and 22/70 eyes (31.4%) for age. The preoperative pupilarysizewas mostly small with 63/70 eyes (90.0%), non-dilated pupils (7/70 eyes) (10.0%). Average pupil size was 3.34 mm (2 - 4mm). Iris condition: iris atrophy 20/10 eyes (28.6%), iris synechiae 11/10 (15.7%), irregular iris muscle with 51, 4% and good iris muscle accounted for 48.6%. Grade of cataract: Grade III: 31/70 eyes (44.3%), Grade IV: 32/70 eyes (45.7%), Grade II: 5/70 eyes (7.1%) and V:2/70 eyes (2.9%). Pupil expander technique: OVD injection with 42/70 eyes (60%), using iris hook with 23/70 eyes (32.9%). Pupillary size before and after intervention has changed from 3.7mm to 4.48mm. Conclusions: Iris expander techniques have been shown to have good dilated pupils: 60.0% OVD injection, iris hook was 32.9%, other methods 7.1% One-week visibility of good visual acuity was higher than that of postoperative one day (12.2%) and increased at 1 month and 3 months (20.0%). Very good visual acuity was not available and low vision group was 1.4% after 3 months. Key words: cataract surgery; phacoemusification, small pupil

Abstract Background To compare visual performance between the iris-fixated phakic intraocular len (pIOL) and implantable collamer len (ICL) to correct high myopia. Methods Twenty-four eyes underwent iris-fixated pIOL implantation and 24 eyes underwent ICL implantation. At the 6-month follow-up, the best-corrected visual acuity (BCVA) and uncorrected distance visual acuity (UDVA) were compared between the iris-fixated pIOL and ICL groups. The objective scatter index (OSI), modulation transfer function (MTF) cutoff, and ocular aberrations were performed to evaluate postoperative visual quality between the two groups. Results No significant difference was found in UDVA, BCVA, and spherical equivalent between the iris-fixated pIOL and ICL groups (P > 0.05). Six months after surgery, the following values were significantly higher in the ICL group than in the iris-fixated pIOL group: MTF cutoff, strehl ratio and optical quality analysis system values at contrasts of 9 %, 20 %, and 100 % (P < 0.01). The OSI in the iris-fixated pIOL group was higher than in the ICL group 6 months after surgery (P < 0.01). All high-order aberrations were slightly more severe in the iris-fixated pIOL group than in the ICL group 6 months after surgery, although only trefoil (P = 0.023) differed significantly in this regard. Conclusions Both iris-fixated lenses and ICLs can provide good visual acuity. ICLs confer better visual performance in MTF-associated parameters and induce less intraocular light scattering than iris-fixated pIOLs.

Abstract Introduction: Choroidal metastases are the most frequent intraocular secondary tumours, with a prevalence of 2–7% according to the literature. Our aim was to review a clinical case of choroidal metastasis. We present a case of a 63-year-old male patient diagnosed in 2018 with lung adenocarcinoma cT4N0M1. The patient had three metastases in the brain, which were successfully treated with radiosurgery (RS). The patient was treated with chemotherapy with pemetrexed–cisplatin schedule. Five months after diagnosis, the patient presented with decreased vision in the right eye. After ophthalmologic evaluation, he was diagnosed with a right choroidal metastasis, which was treated with external beam radiotherapy with 20 Gy in five fractions, resulting in improved visual acuity and a complete clinical and radiological response. The patient took part in a clinical trial that continued with systemic chemotherapy. Twenty-two months after radiotherapy to the eye, the patient has good visual acuity without any side effects. Conclusions: Choroidal metastasis treated with radiotherapy achieves good local control, with limited side effects, allowing an improvement in visual acuity and consequently, an improvement in the patient´s quality of life.
