“…In other species of parrots, some of reported ophthalmological disorders are: exophthalmos secondary to squamous cell carcinoma at the infraorbital sinus in a Solomon Island eclectus parrot (Eclectus roratus solomonensis) (Diaz-Figueroa et al 2006) and secondary to a retrobulbar adenoma in an African grey parrot (Psittacus erithacus) (Simova-Curd et al 2009); periorbital liposarcoma was also described in this species (Psittacus erithacus) (Graham et al 2003); Horner's syndrome secondary to trauma in a Redbellied parrot (Poicephalus rufiventris) (Gancz et al 2005), and mycobacterial keratitis in a Maximilian's parrot (Pionus maximiliani maximiliani) (Stanz et al 1995).…”

Retrospective study of ocular disorders in Amazon parrots

A retrospective study was conducted to identify the occurrence and types of ocular disorders in 57 Amazon parrots admitted to the Ophthalmology Service, Veterinary Teaching Hospital, School of Veterinary Medicine, University of São Paulo, Brazil from 1997 to 2006. The most frequent observed disorder was cataracts, present in 24 of the 114 examined eyes (57 parrots). Uveitis, ulcerative keratitis and keratoconjunctivitis were frequently diagnosed as well. The cornea was the most affected ocular structure, with 28 reported disorders. Uveal disorders also were commonly observed. Conjunctiva and eyelid disorders were diagnosed in lower frequency. Results suggest that cataracts are common and that cornea, lens and uvea are the most affected ocular structures in Amazon parrots.

“…The wedge‐tailed eagle presented with miosis rather than mydriasis, with the latter being an expected response to catecholamine derivatives in all domestic species. Birds exhibit conscious control of pupillary action due to the dominance of striated muscle fibres in the avian dilator muscle and show miosis variably during organophosphate poisoning 11 . Miosis can also be observed in birds following elevated intracranial pressure and acute uveitis 12,13 .…”

“…Normal STT-1 values [2,6,8,12,35,38,39] and IOP values measured with the Tonovet® rebound tonometer have been reported for various domestic and wild animals [1,2,5,9,12,14,24,30,35,[40][41][42]. However, very limited information is available on these ocular parameters in penguins living in their natural Antarctic habitat.…”

According to literature review, this is the first study investigating tear production and intraocular pressure in pygoscelid penguins living in their natural habitat. This study also provides reference values for penguins kept under professional care at zoos and rehabilitation centres. This study aimed to establish normal values for standard ocular tests, including the Schirmer tear test (STT-1) and intraocular pressure test (IOP), for penguins belonging to the genus Pygoscelis (P), namely, the Adélie (Pygoscelis adeliae), gentoo (Pygoscelis papua) and chinstrap (Pygoscelis antarctica) penguins. Ophthalmic measurements were made from the Antarctic. In the left eye of each penguin, the amount of tear production (TP) was determined with the STT-1 and the IOP was measured using a Tonovet® rebound tonometer. No macroscopic findings affecting the eyelids, third eyelid, cornea or anterior eye camera were detected in the eyes of the examined penguins. The mean STT-1 and mean IOP values of 129 and 120 adult penguins were determined as 10.163 ± 4.054 mm/min and 38.852 ± 13.188 mmHg, respectively. A statistical difference at the level of p < 0.001 was determined between the islands for the mean IOP values. While no statistically significant difference was detected between the penguin species for the mean IOP values, between the locations was found to be significant (p < 0.001). Statistical differences at a level of p < 0.05 were determined for the mean TP values between the all locations and for the mean IOP values between the all locations ( p < 0.001) and only Lions Rump - Ardley I (p = 0.023). A statistical difference of p < 0.05 was detected between the chinstrap and gentoo for the mean STT-1 values. This study, which is aimed at reporting the first literature data in this field, has shown the need for further more detailed studies to elucidate the impact of different locations, daily time intervals and seasons on the STT and IOP values of penguins.
