In 15 eyes (75%) the retinal lesions were associated with intraocular inflammation. Vitreoretinal complications were observed in eight eyes (29.6%), with 22.7% of them requiring vitreous surgery. [elsevier.es]
Older patient age was significantly associated with: posterior pole lesions (0.003), larger retinal lesion sizes (p=0.001) and multiple lesions (p=0.001). [omicsonline.org]

- Blurred Vision
Suddenly blurred vision, floater, and pain could be caused by Toxoplasma gondii. Flashing, may necessitate a more precise peripheral fundus examination. [ncbi.nlm.nih.gov]

- Photophobia
A 28-year-old man presented with a 2-week history of red eye, photophobia, pain and decreased visual acuity of the right eye. [ncbi.nlm.nih.gov]
Case summary: A 48-year-old man presented with a 1-week history of red eye, photophobia, eyeball pain, and decreased visual acuity of the left eye. Best corrected visual acuity was 20/200 in the left eye and 20/20 in the right eye. [evrs.eu]
Symptoms of ocular disease include Eye pain Sensitivity to light (photophobia) Tearing of the eyes Blurred vision The eye disease can reactivate months or years later, each time causing more damage to the retina. [cdc.gov]
The patients present a photophobia and floaters are seen. The slit-lamp examination reveals the presence of a granulomatous inflammation, a mild to moderate anterior chamber inflammation. [medsci.org]
Other complaints included photophobia, ocular pain, floaters and redness were comparable to presenting complaints seen in Kaduna, Nigeria, where reduced vision was the most common presenting complaint followed by photophobia, pain, irritation, redness [jovr.org]
- Retinal Pigmentation
Human retinal pigment epithelial (RPE) cells (ARPE-19) were infected in vitro with T. gondii and collected after 60, 120, 240 min, and 24 h. [ncbi.nlm.nih.gov]
Optical coherence tomography (OCT) revealed left optic disc swelling, cysoid macular edema, and retinal pigment epithelial atrophy. Pupillary light reflex and color vision were normal. [evrs.eu]
Contd In Immunosuppressed Have both tachyzoites and tissue cysts in areas of retinal necrosis and within retinal pigment epithelial cells. Parasites can occasionally be found in the iris, choroid, vitreous, and optic nerve 10. [slideshare.net]
Using either route, parasites were observed in the retinal vessel with the formation of a glial reaction in the inner plexiforme layer and discontinuity of the pigmented epithelium of the retina 7 days after infection. [cambridge.org]
- Eye Pain
Symptoms of ocular disease include Eye pain Sensitivity to light (photophobia) Tearing of the eyes Blurred vision The eye disease can reactivate months or years later, each time causing more damage to the retina. [cdc.gov]
The symptoms and signs of ocular toxoplasmosis in immunosuppressed patients include decreased vision and eye pain. However, the eye disease may be more severe, especially in elderly patients [ 13 ]. [entokey.com]
Eye pain and redness if the patient has a secondary iritis. Clinical diagnosis Clinical evaluation and diagnosis is the most important part of diagnosing toxoplasmosis retinitis. [eyewiki.aao.org]
An infection in the eye is called ocular toxoplasmosis. Symptoms may include: Eye pain. Poor vision. Floaters, which are specks that seem to swim in your vision. Untreated eye disease can cause blindness. [mayoclinic.org]

Workup
They usually resolve after 6 weeks. [21] Workup Fluorescein angiography Fluorescein angiography (FA) of active lesions shows hypofluorescence during the early phase of the study, followed by progressive hyperfluorescence secondary to leakage. [emedicine.medscape.com]
Imaging is paramount not only to detect but also to characterize CNS disease, and ultimately to guide decision making on further diagnostic workup or therapeutic management. [pubs.rsna.org]
Treatment
The need for therapy, type of drug treatment and duration of therapy needs to be individualised. [nps.org.au]

The side effects of each of these drugs need to be considered along with the benefits of the treatment. Further randomized clinical trials are required to determine the best standardized treatment protocol. [cochranelibrary.com]
Prognosis
To report the clinical course and prognosis of retinal breaks and detachments occurring in patients with ocular toxoplasmosis. [ncbi.nlm.nih.gov]
Prognosis The prognosis is poor when congenital toxoplasmosis is acquired during the first three months of pregnancy. [medical-dictionary.thefreedictionary.com]
Prognosis Retinochoroiditis is the most frequent manifestation of congenital toxoplasmosis. [eyewiki.aao.org]
Long-term ocular prognosis in 327 children with congenital toxoplasmosis. [scielo.br]
Etiology
The possibility of retinal ischemia or inflammation alone as an etiology are discussed. A 19 year old woman developed optic nerve edema and a marked decrease in vision associated with a nasal toxoplasma lesion and a macular star. [ncbi.nlm.nih.gov]
Presentation History The history may suggest an etiology and may reveal clues concerning the likelihood of an infectious etiology. [emedicine.medscape.com]
The clinical findings may overlap between different etiologies. [intechopen.com]
Epidemiology
Considering the local epidemiological data, our OT patients seemed to be infected more frequently by ordinary type II strains found in the environment. [ncbi.nlm.nih.gov]
Purpose To report the epidemiological, clinical and prognostic features of ocular toxoplasmosis in an immigrant population in the Barcelona area. [elsevier.es]
Pathophysiology
The aim of the present review was to report on the results of a survey of leading uveitis experts, in which the authors asked participants to address some of the most important issues related to diagnosis, pathophysiology, and treatment of ocular toxoplasmosis [ncbi.nlm.nih.gov]
Pathophysiologic and Clinical Issues. [pubs.rsna.org]
Prevention
Prevention of Recurrences Prevention of recurrences of toxoplasmic retinochoroiditis may prevent loss of vision. Patients with paramacular toxoplasmosis may be given antimicrobial prophylaxis to prevent recurrences. [aao.org]
We present 2 cases of recurrent OT in immunocompetent patients for whom prophylaxis prevented recurrence of disease. [ncbi.nlm.nih.gov]
Hence to highlight this blinding disease, which may escape detection and to emphasize its preventive measures so as to prevent the visual disability arising from it. [mjdrdypu.org]
Drugs that prevent the rejection of transplanted organs. Prevention Certain precautions can help prevent toxoplasmosis: Wear gloves when you garden or handle soil. Wear gloves when you work outdoors. Wash your hands with soap and water afterward. [mayoclinic.org]
